“When he went out

To the porch,

Another servant girl

Saw him.

She said

To the bystanders.

‘This man was

With Jesus of Nazareth.’

Again,

He denied it

With an oath.

‘I do not know

The man.’”

 

ἐξελθόντα δὲ εἰς τὸν πυλῶνα εἶδεν αὐτὸν ἄλλη καὶ λέγει τοῖς ἐκεῖ Οὗτος ἦν μετὰ Ἰησοῦ τοῦ Ναζωραίου.

καὶ πάλιν ἠρνήσατο μετὰ ὅρκου ὅτι Οὐκ οἶδα τὸν ἄνθρωπον.

 

This is similar to Mark, chapter 14:69-70, Luke, chapter 22:58, and John, chapter 18:25, with some minor changes, as all 4 gospels have this 2^nd denial of Peter.  In Mark, it is the same servant-girl rather than a different one.  In John, it was a group of people rather than one individual who addressed Peter.  Matthew said that Peter went out to the porch area of the courtyard (ἐξελθόντα δὲ εἰς τὸν πυλῶνα).  Another young servant girl or maid saw him (εἶδεν αὐτὸν ἄλλη).  She then said to the bystanders there (καὶ λέγει τοῖς ἐκεῖ) that this man was with Jesus of Nazareth (Οὗτος ἦν μετὰ Ἰησοῦ τοῦ Ναζωραίου).  Again, Peter denied it with an oath (καὶ πάλιν ἠρνήσατο μετὰ ὅρκου).  He said that he did not know this man (ὅτι Οὐκ οἶδα τὸν ἄνθρωπον).  Peter, the great defender of Jesus, again denied him in public with a solemn oath for a 2^nd time, something he said that he would never do.  Jesus had warned them about swearing oaths in chapter 5:33-37.
